Claims (10)

  1. Compresseur à anneau liquide, caractérisé par un rotor intérieur excentrique (6) supporté au niveau des axes (8, 9) dans un co-rotor extérieur (3) pour l'anneau liquide, le palier des co-rotors (11) étant situé à l'extérieur des mêmes axes et enfermé de chaque côté dans une enceinte où un joint à lèvre rotatif (82) est disposé de part et d'autre du palier (11), ladite lèvre (83) dudit joint à lèvre (82) vient en contact avec les axes (8, 9) à faible vitesse et ladite lèvre (83) fait saillie à grande vitesse en raison de forces centrifuges et se soulève des axes, des trous traversants (81) étant prévus à travers les parois latérales du co-rotor et l'enceinte du palier, lequel volume à l'intérieur de l'anneau liquide est évacué vers l'enceinte (1) qui l'entoure de sorte à ne pas générer de pression différentielle à travers les paliers et les joints des paliers.
  2. Compresseur selon la revendication 1, caractérisé en ce que le rotor (6) présente au niveau de la périphérie un certain nombre de cellules (61) de forme demi-cylindrique, l'arc étant tourné vers le centre.
  3. Compresseur selon les revendications 1 à 2, caractérisé en ce que les cellules (61) du rotor (6) présentent des ouvertures de canal radiales (62) de chaque côté entourées par une section lisse circulaire (63) permettant d'assurer l'étanchéité avec un commutateur stationnaire (7) placé au centre du rotor.
  4. Compresseur selon les revendications 1 à 3, caractérisé en ce que du liquide est injecté depuis le trou (75) dans le commutateur (7) dans la zone de compression, des jets de liquide sortant des rebords de l'ouverture de canal (62) vers les cellules (61) du rotor.
  5. Compresseur selon les revendications 1 à 4, caractérisé en ce que le commutateur (7) présente de chaque côté des rainures périphériques (71), dans lesquelles du liquide d'injection est sous pression et empêche les fuites de gaz.
  6. Compresseur selon les revendications 1 à 5, caractérisé en ce que la périphérie du commutateur (7) est à l'extérieur des joints de palier des co-rotors de sorte que l'eau s'échappant de l'espace entre le commutateur et le rotor est projetée dans l'anneau liquide sans passer par les joints de palier.
  7. Compresseur selon les revendications 1 à 6, caractérisé en ce que les paliers (11) pour le co-rotor sont des paliers de type à bille ou à rouleau.
  8. Compresseur selon les revendications 1 à 6, caractérisé en ce que des paliers (11) sont des paliers lisses, y compris de type hydrodynamique.
  9. Utilisation d'un compresseur selon les revendications 1 à 8, comme compresseur d'air et de gaz compatibles avec l'eau, l'eau étant utilisée comme liquide d'injection.
  10. Utilisation d'un compresseur selon les revendications 1 à 9, comme un compresseur dans une installation de turbine à gaz.
